One of the objects of this invention therefore is to provide and improve flush-tank and water closet construction having a configuration capable of conducting the accumulated by sweating on the outside of the tank to a drain by way of the water closet.

Flush-tank sweating has long been a recognized problem which results from the passage of cold water to the flush-tank system, said flush-tank being located in an ambient atmosphere of high relative humidity. Three major arrangements have been devised for preventing said sweating namely, insulated tanks, double wall tanks, and trays for collecting the moisture and piping the same into the drain.

The preferred embodiment of my invention utilizes structure not heretofore found in this field by incorporating a new configuration to the bottom wall of the flush-tank. The bottom wall of the flush-tank is sloped from the outer edges downwardly as it approaches the center of the tank. This sloping bottom wall conducts the accumulated moisture to the area immediately above the rear portion of the water closet. The top of the water closet is provided with a slightly raised rim and a sloping depressed area surrounding the usual opening for the water pipe from the flush-tank. The sloping depressed area has a downwardly slope towards the bowl opening at the rear thereof, and any moisture collected on the rear of the water closet flows by gravity into the bowl and thus is disposed of in the sewer.

Accordingly, it is another object of this invention to provide a water closet top wall having a sloped area with a raised rim there around for collecting condensation dripping from a flush-tank there above and thereby draining same by gravity into the bowl of the water closet.

A still further object of this invention is to provide a flush-tank for a water closet having a lower wall sloping downwardly toward the center thereof and a water closet with an upper surface sloping towards the center line thereof in substantial parallelism with the said flush-tank, said sloping top having a downwardly sloping trough into the bowl of the water closet.

Other objectsand advantages more or less ancillary to the foregoing and the manner in which all the various objects are realized, will appear in the following description, which, considered in connection the accompanying drawings, set forth in the preferred embodiment of the invention.

IN THE DRAWINGS nated generally by the numeral 10 and a water closet designated by the numeral 12.

The flush tank 10 is generally rectangular and is provided with a top 14 and a bottom 16. An opening 18 is provided centrally in the bottom wall 16 and is available for discharging the contents of the tank 10. The bottom wall 16 is sloped downwardly towards the opening 18 from the intersection of the bottom 16 with the sides of the tank 10.

The intersection of the planes of the sides of the tank 10 with the bottom 16 is rounded to eliminate a sharp edge at the lower end of the tank 10. The rounded corner 20 preferably should have a radius approximately three-fourths of an inch. The slope of the bottom wall should be pitched downwardly from 5 to 10 below the horizontal. Condensation on the sides of the tank 10 will fiow by gravity around the edge 20 and along the sloped bottom wall 16 of the tank 10 to the area adjacent to the opening 18 where it is dropped on the water closet 12 below.

The flush-tank 10 is provided with a fill opening 22 and mounting holes 24 for mounting the flush-tank 10 on the water closet 12. Y

The water closet 12 has a top 26 on which the tank 10 is mounted. The closet top 26 has an opening 28 on which the opening 18 is superimposed to provide a passage for the discharge of the contents of the tank 10 to the opening 18 and the opening 28 into the water closet 12. The top 26 is provided with a rim 30 raised approximately one-fourth of an inch above and extending around the periphery of the top 26 in the area'beneath the tank 10. The bottom 16 of the tank 10 is spaced above the rim 30 in order that the moisture will flow along the bottom of the tank 16 over the rim 30 and be discharged on the top 26 of the water closet 12. The water closet 12 has a bowl opening 32 which receives the condensation from the tank 10 as it flows across the top 26 of the water closet and to the bowl opening 32. The central portion of the top 26 of the water closet between the opening 28 and the opening 32 is provided with a downwardly slope toward the opening 32 as best illustrated in detail in F IG.'5. This facilitates the flow of condensation into the bowl opening 32 and discharge to the sewer.

As the condensation accumulates on the outside of the tank 10 it flows down the walls of the same round the rounded edge 20 and across the downwardly sloping bottom 16 toward the opening 18. The condensation falls by gravity to the top 26 of the water closet where it is collected in the areas surrounded by the rim 30. The condensation then flows by gravity along the sloping section 34 of the top 26 and is discharged into the bowl opening 32 of the water closet 12.

What is claimed is:

l. A water closet comprising a flush-tank, having outer walls and a bottomwall, said bottom wall being sloped downwardly from the outer walls toward the center of the tank, and a water closet bowl beneath the flush-tank, said bowl a top wall for carrying said tank said tank joining said top wall at the central portion of said tank, said top wall said rim being a vertical rim there around, having spaced from the joinder of said tank with the top wall to the bowl, said water closet top wall being sloped toward the bowl opening of the water closet.

of the flush-tank is rounded to conduct the condensation there around as it collects on the flush-tank and I flows by gravity to the water closet top bowl. 

1. A water closet comprising a flush-tank, having outer walls and a bottom wall, said bottom wall being sloped downwardly from the outer walls toward the center of the tank, and a water closet bowl beneath the flush-tank, said bowl a top wall for carrying said tank said tank joining said top wall at the central portion of said tank, said top wall said rim being a vertical rim there around, having spaced from the joinder of said tank with the top wall to the bowl, said water closet top wall being sloped toward the bowl opening of the water closet.
 2. The water closet of claim 1 wherein the top wall of the water closet has a vertical rim around outer margin of the area beneath the flush-tank.
 3. The water closet of claim 1 wherein the edge formed by the joinder of the side walls and bottom wall of the flush-tank is rounded to conduct the condensation there around as it collects on the flush-tank and flows by gravity to the water closet top bowl.
